MUSLIM, Book 032, Number 6303:
Humaid b. 'Abd al-Rahman b. 'Auf reported that his mother Umm Kulthum daughter of 'Uqba b. Abu Mu'ait, and she was one amongst the first emigrants who pledged allegiance to Allah's Apostle (may peace be upon him), as saying that she heard Allah's Messenger (may peace be upon him) as saying: A liar is not one who tries to bring reconciliation amongst people and speaks good (in order to avert dispute), or he conveys good. Ibn Shihab said he did not hear that exemption was granted in anything what the people speak as lie but in three cases: in battle, for bringing reconciliation amongst persons and the narration of the words of the husband to his wife, and the narration of the words of a wife to her husband (in a twisted form in order to bring reconciliation between them).
Ibn Shihab mengatakan bahwa dia tidak mendengarkan PENGECUALIAN untuk BERBOHONG kecuali untuk tiga kasus berikut ini: dalam perang, untuk membawa rekonsiliasi dan dalam pembicaraan / perbincangan / penjelasan suami kepada istri, dalam pembicaraan / perbincangan / penjelasan istri kepada suami (dalam bentuk yang dipelintir/diputar-balik untuk membawa rekonsiliasi diantara mereka).
BUKHARI, Volume 3, Book 49, Number 857:
Narrated Um Kulthum bint Uqba:
That she heard Allah's Apostle saying, "He who makes peace between the people by inventing good information or saying good things, is not a liar."
Um Kulthum bint Uqba Menceritakan: Dia mendengar rasul allah berkata, "Seseorang yang membawa kedamaian dengan membuat-buat/memalsukan informasi dan hal-hal yang baik BUKANLAH seorang PENIPU"
DAN inilah BUAH AJARAN MENIPU itu:
Suatu waktu si nabi penipu memiliki MUSUH namanya Ka'b bin Al-Ashraf. Karena si nabi palsu itu memang chicken coward alias bloody chicken, dia lalu menyuruh pengikutnya Muhammad bin Maslama untuk membunuh Ka'b. Bagaimana cara membunuhnya? Yah GAMPANG!....dengan caran MENIPU!...rasul allah penipu itupun mengijinkan pengikutnya membunuh dengan CARA MENIPU!....
Akhir cerita Maslama emang berhasi membunuh musuh si nabi cabul, Ka'b. Namun caranya adalah dengan PURA-PURA baik dan mencium wewangian yang ada di kepala Ka'b. Setelah Ka'b lengah, Maslama pun mencekiknya sampai MATI!...
BUKHARI, Volume 5, Book 59, Number 369:
Narrated Jabir bin 'Abdullah:
Allah's Apostle said, "Who is willing to kill Ka'b bin Al-Ashraf who has hurt Allah and His Apostle?" Thereupon Muhammad bin Maslama got up saying, "O Allah's Apostle! Would you like that I kill him?" The Prophet said, "Yes," Muhammad bin Maslama said, "Then allow me to say a (false) thing (i.e. to deceive Kab). "The Prophet said, "You may say it." Then Muhammad bin Maslama went to Kab and said, "That man (i.e. Muhammad demands Sadaqa (i.e. Zakat) from us, and he has troubled us, and I have come to borrow something from you." On that, Kab said, "By Allah, you will get tired of him!" Muhammad bin Maslama said, "Now as we have followed him, we do not want to leave him unless and until we see how his end is going to be. Now we want you to lend us a camel load or two of food." (Some difference between narrators about a camel load or two.) Kab said, "Yes, (I will lend you), but you should mortgage something to me." Muhammad bin Mas-lama and his companion said, "What do you want?" Ka'b replied, "Mortgage your women to me." They said, "How can we mortgage our women to you and you are the most handsome of the 'Arabs?" Ka'b said, "Then mortgage your sons to me." They said, "How can we mortgage our sons to you? Later they would be abused by the people's saying that so-and-so has been mortgaged for a camel load of food. That would cause us great disgrace, but we will mortgage our arms to you." Muhammad bin Maslama and his companion promised Kab that Muhammad would return to him. He came to Kab at night along with Kab's foster brother, Abu Na'ila. Kab invited them to come into his fort, and then he went down to them. His wife asked him, "Where are you going at this time?" Kab replied, "None but Muhammad bin Maslama and my (foster) brother Abu Na'ila have come." His wife said, "I hear a voice as if dropping blood is from him, Ka'b said. "They are none but my brother Muhammad bin Maslama and my foster brother Abu Naila. A generous man should respond to a call at night even if invited to be killed." Muhammad bin Maslama went with two men. (Some narrators mention the men as 'Abu bin Jabr. Al Harith bin Aus and Abbad bin Bishr). So Muhammad bin Maslama went in together with two men, and sail to them, "When Ka'b comes, I will touch his hair and smell it, and when you see that I have got hold of his head, strip him. I will let you smell his head." Kab bin Al-Ashraf came down to them wrapped in his clothes, and diffusing perfume. Muhammad bin Maslama said. " have never smelt a better scent than this. Ka'b replied. "I have got the best 'Arab women who know how to use the high class of perfume." Muhammad bin Maslama requested Ka'b "Will you allow me to smell your head?" Ka'b said, "Yes." Muhammad smelt it and made his companions smell it as well. Then he requested Ka'b again, "Will you let me (smell your head)?" Ka'b said, "Yes." When Muhammad got a strong hold of him, he said (to his companions), "Get at him!" So they killed him and went to the Prophet and informed him. (Abu Rafi) was killed after Ka'b bin Al-Ashraf."
